What is the ASP.NET AJAX Control Toolkit?

The ASP.NET AJAX Control Toolkit is an open-source project built on top of the Microsoft ASP.NET AJAX framework.
It is a joint effort between Microsoft and the ASP.NET AJAX community that provides a powerful infrastructure to write reusable,
customizable and extensible ASP.NET AJAX extenders and controls, as well as a rich array of controls that
can be used out of the box to create an interactive Web experience.

The AJAX Control Toolkit contains more than 30 controls that enable you to easily create rich, interactive web pages.
